Deeper analysis
Microsoft Internet Explorer 11 contains a memory corruption vulnerability tracked as CVE-2015-2425 and assigned CWE-787. The flaw permits out-of-bounds writes when the browser processes specially crafted web content, leading to arbitrary code execution or denial of service. It is distinct from the related issues CVE-2015-2383 and CVE-2015-2384 and carries a CVSS 3.1 base score of 8.8 reflecting network attack vector, low complexity, and high impact on confidentiality, integrity, and availability.
An unauthenticated remote attacker can exploit the issue by convincing a user to visit a malicious website under the attacker's control. Successful exploitation grants the ability to execute arbitrary code in the context of the current user or to crash the browser process.
Microsoft addressed the vulnerability in security bulletin MS15-065, which supplies patches for affected builds of Internet Explorer 11. The bulletin and corresponding SecurityTracker entries recommend applying the updates as the primary mitigation; no additional configuration changes are specified in the references.
The vulnerability appears in the CISA Known Exploited Vulnerabilities catalog, indicating confirmed real-world exploitation activity.
